Design Features
The Industrial Lobe Series pumps are designed to handle fluids of nearly any viscosity, especially shear sensitive materials, at higher pressures than an internal gear pump or a standard lobe pump is capable of. The high pressure option uses a patented shaft support system with bushings on both sides of the bi-wing rotors to allow higher pressures and reduce wear on bushings and seals. An adjustable bearing housing allows simple end clearance adjustment. These pumps accept a wide variety of cartridge-style seals from most major manufacturers, including single mechanical, double mechanical and triple lip seals. The two smaller sizes also accept component single mechanical seals or shaft packing. A variety of porting options allows the ports to be correctly sized for the application. The Industrial Lobe Series includes the following models:
